Your documents do not have system IDs. This is malformed according

If JDOM's allowing to create documents like this, then that's a bug
that needs to be fixed.
A quick look at the code of DocType shows that there's no test
whether the public or system ID is null. This should probably be
fixed.
More importantly, there's a design flaw in this class. The empty
string is a legal public ID. However, we don't distinguish between
the empty string as a public ID and no public ID at all. We should
probably allow null public IDs to indicate that there is only a
system ID. That is, change
public DocType(String elementName, String systemID) {
this(elementName, "", systemID);
}
to
public DocType(String elementName, String systemID) {
this(elementName, null, systemID);
}
The system ID can also legally be the empty string so we also need to change
public DocType(String elementName) {
this(elementName, "", "");
}
to
public DocType(String elementName) {
this(elementName, null, null);
}
The next step is to change the XMLOutputter and SAXBuilder and
DOMBuilder logic to use null to indicate no public ID and no system
ID instead of the empty string. More on that shortly.
